I was about to mention the very same guy. Groves and Avila are definitely more skilled than most BIg 12 and SEC bigs, but there's a risk of getting the destroyed on the boards for both of them. And with so much ball screen action in these leagues they either force their teams to play an inordinate amount of zone or risk getting killed on ball screen actions repeatedly throughout the game. That being said, they typically excel in tournaments and one off games because they're not scouted to death like they are in conference games. Although he's much more athletic than both Groves and Avila, Grant Nelson struggled in a similar fashion this past season in the SEC. His rebounding #s were essentially cut in a half where he went from a DR% of 26.7% in 22-23 to 17.3% this past season in the Big 12. And much like I mentioned above about skilled bigs like these guys excelling in the tourney, Nelson was arguably Bama's best player as the importance of the tourney games increased.
